SHEDDING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 558,221, dated April14, 1896. Application filed February 18,1892. Renewed September 5, 1895.Serial No. 561,752. (No model.)

To col], whom it may concern.-

Be it known that LALBERT SN OECK,of Hartford, Hartford county,Connecticut, have invented an Improvement in Shedding Mechanism forLooms, of which the following description, in connection with theaccompanying drawings, is a specification, like letters and figures onthe drawings representing like parts.

Fancy-looms containing upright levers having attached jacks, as inUnited States Patent No. 77,361, dated April 28, 1868, and in the formof fancy-loom represented by United States Patent No. 134,992, datedJanuaryzl, 1873, have in practice been provided withpattern-chains,substantially such as represented in United States PatentNo. 363,367, dated May 24, 1887, said chains being composed of a seriesof bars having rolls or protuberances. In practice these chains containanywhere y from twelve to five hundred bars, according to the intricacyof the pattern or the number of picks in the design. The order ofdistribution of the jacks to control the order of shedding depends uponthe peculiar location of the projections and spaces on the successivebars of the pattern-chain, and in setting up a chain for the productionof a particular pattern great care has to be taken to avoid mistakes,and only a careful hand can be depended upon for this work. The settingup of the rolls and spaces on the consecutive bars of the chain andpushing the bars in the links of the chain and joining the linkstogether is also a slow and tedious operation-as, for instance, it willrequire about two days time of a good workman to set up a pattern-chainhaving four hundred bars. This class of chain is quite expensive tomake, and I being of metal is, it 'will be obvious, quite heavy, and thelonger the chain the greater the power required to work it. These chainsare further objectionable because of their lack of durability, as inpractice the joints of the chain-links and the bars wear, so that thechain fails to register with the cylinder as when new, and the rolls andtubes on the bars wear, so that they fail to operate the jacksuniformly, and as a result thereof mispicks are occasioned.Occasionally, because of a flaw or otherwise, part of a roll breaks outand in such case there is a mispick.

v out leading chains up or down into another room, which is not aninfrequent occurrence. This my present invention has forits object toavoid the use of these metallic patternchains, and in doing this I haveprovided an endless -belt-like pattern-surface, which is thoroughlyflexible, yet strong and durable, and have combined with it a series ofneedles acted upon directly at one end by the patternsurface andprovided with eyes for the reception of selecting-rods, which are madeto slide longitudinally in said eyes by means of a jack-elevator, thelatter acting upon such ones of the selecting-rods as are put in thepath of its movement by the needles acted upon by the pattern-surface,the said selecting-rods acting directly upon fingers which in turn actagainst notched jacks connected with harness levers, so that saidnotched jacks are put into position to be acted upon one or the other oftheir projections by a suitable lifter or depressor common to the saidCrompton orto the said Knowles type of loom. The Jacquardpattern-surface used will be made of a web of paper, the paper beingpref- 8o erably strengthened by a fabric. The tougher the nature of thepaper the longer the life of the pattern-surface.

The pattern-surface in accordance with my invention hangs on asubstantially cylindrical 8 5 roll or barrel having holes, the paperbeing provided with holes distributed according to the requirements ofthe pattern in usual manner.

In the practice of my invention, as herein illustrated, the roll orbarrel carrying the paper pattern is rotated intermittingly to bring aproper row of holes in position and then moved toward and against theends of the needles to cause the selecting-rods cooperat- 5 ing with thejacks to be lifted to be placed or kept within the range of movement ofthe jack-elevator and to enable the roll or barrel to have thesemovements in the proper time, direction, and order without injury to themo parts and yet enable the roll or barrel to be rotated by a pawldevice, as usual, I have had to provide means to rotate thepattern-surface as it approaches the needles and to prevent furtherrotation of the barrel after the pattern-surface is in contact with andis mov ing the needles. -As shown in Figures 1 and 2, I have done thisby mounting the pawl on a movable fulcrum, so that the pawl may fol lowthe roll or barrel during the time that the pattern-surface is incontact with the needles; but this part of my invention is not to belimited to the exact devices shown for this purpose.

It will be obvious that the employment of a Jacquard pattern-surface,composed of a nonmetallic light-weight, cheap, flexible materialcomparatively inexpensive, is a matter of very considerable importanceto manufacturers, for by using any of the various machines or devicesemployed for punching ordinary Jacquard cards pattern-surfaces suitablefor use in a loom containing my improvements may be rapidly andinexpensively made, and a great number of different patterns might bemade while one pattern was being set up by bars or rolls and links, and,if desired, owing to the nature of the material used by me for thepattern-surface, several like pattern-sun faces may be produced at oneand the same operation to go onto several different looms to weave thesame pattern.

By the employment of a pattern-surface of the kind mentioned it will beapparent that the pattern-surface may, whenever it is desired to changea loom from one to another pattern, be quickly slipped off and laid awayand another pattern-surface be quickly applied to the loom, thepattern-surface laid away, it having cost substantially nothing, exceptthe labor of cuttingholes therein, being ready for reuse at any timedesired, which it is obvious can not be done with the metallicpattern-chains without immense cost and without great storage conditionsin the factory.

One part of my invention consists, essentially, in a loom containing thefollowing instrumentalities, viz: a series of harness-levers, a seriesof notched jacks connected thereto, a thin flexible belt-likepattern-surface provided with holes, means to carry saidpattern-surface, a series of needles acted upon directly by saidpattern-surface, a series of selecting-rods carried by and slidinglongitudinally in eyes or guides in said needles, a series of pivotedfingers acted upon by the selecting-rods and cooperating with the jacksto lift them, and a j ack-elevator to act against and slide certain ofthe selecting-rods to move the fingers and to lift certain of thenotched jacks according to the requirements of the pattern-surface,substantially as will be described.

Otherfeatu res of my invention will be hereinafter set forth in thespecification and included in the claims at the end thereof.

Fig. 1 is a sufficient portion of one end of a loom containing myimprovements to enable my invention to be understood. Fig. 2 is a frontelevation of that part of the loom shown in Fig. 1. Fig. 3 is a rearside elevation of the part of the loom shown in Fig. 1. Fig. 4 is apartial section in the line as, Fig. 1. Fig. 5 shows a modification ofmy invention to be described. Fig. 6.is an enlarged detail, showing oneend of the roll or barrel carrying the belt-like pattern-surfacecomposed of paper and cloth, the paper being partially torn away to notonly show the cloth, but also to show the carrying studs or pins at oneend of the roll or barrel. Fig. 7 is a detail showing one of the needleswith its eye for-guiding a selecting device. Fig. 8 is a section in theline 00 of Fig. 6, and Figs. 9 and 10 views of yet another modificationshowing a pawl with a fixed fulcrum to rotate the pattern-barrelcarrying the pattern-surface.

Referring to the drawings, A represents a part of the side frame of aloom, and A an extension to sustain the shed-forming mechanism. Arepresents a portion of the crankshaft of the loom, it having inpractice usual cranks, which are joined by connecting-rods to the lay,(not shown,) but which may be of any known or suitable construction.

In Figs. 1 to 4 I have shown my invention as applied in connection withan upright lever B, having arms or projections B, upon which are pivotedsuitable notched jacks B said levers and jacks being of the kind commonto United States Patent to Crompton,No. 7 7 ,361, and in practice thesaid jacks will be engaged by lifters or by depressors, as provided forin said patent, prior to the formation of each shed, and in practice theupper and lower ends of the said levers will be joined by suitablecording to usual harnessframes, substantially as common to the saidCrompton or other form of loom having shedforming levers provided withnotched jacks.

The crank-shaft A at one end has fast upon it a beveled gear A, whichengages a beveled gear A fast on and rotating a shaft A provided withcams O and D, the cam C acting upon an arm 0 attached to a shortrock-shaft 0 having a second arm 0 provided at its upper end with aslot, which is entered by a stud O" in one end of a link 0 jointed atits other end in suitable manner to an arm 0 of a rock-shaft C suitablymount-ed in part of the framework, the said rock-shaft having an armupon which is pivoted a locking device C shown as a spring-controlledlever having at one end a roll adapted to enter cavities in a disk orwheel E (shown best in Fig. 1) attached to the shaft E of the substantially cylindrical roll or barrel E carrying the Jacquardpattern-surface E composed of strong paper or other textile materialunited together at its ends to form an endless flexible belt. The shaftE has its bearings in suitable arms F1 attached to the shaft 0 so thatthe said roll or barrel carrying the pattern-surface is vibrated attimes by the shaft 0 as a center of motion. The

roll or barrel is provided with holes, and the pattern-surface is alsoprovided with suitable IIC the framework.

holes, as a, a portion'only of which are represented in Fig. 1, and asthe said pattern-surface is moved in the direction of the arrow near it,Figs. 4 and 5, as provided for in this present embodiment ofmyinvention, wherever an unbroken part of the pattern-surface comesagainst the end of a needle (1, of which there are a series, one foreach jack, then the said needle is moved to the right, viewing Figs. 4and 5; but if there is a hole in the pattern-surface then the needle isnot acted upon, but remains at rest. The barrel orpattern surface isvibrated, as described, and made to contact with the needles previous tothe formation of each shed. i

The ends or other portions of the needles more or less remote from thepattern-surfaces are suitably bent or shaped to form eyes a as bestrepresented in Figs. 4 and 7, through which are extended loosely theselecting-rods a suitably guided at their upper ends in guides a andpreferably each selecting-rod willihave an enlargement a (see Fig. 4);above theguide to prevent the descent of the} selecting-rod below adefinite determined} point, said selecting devices slidinglongitudinally directly in the eyes of the needles acted upon directlyby the pattern-surface.

I11 Fig. 4 I have shown some of the selecting-rods as thrown out of linewith relation to other of the selecting-rods-viz. those selecting-rodscooperating with the needles which have been moved longitudinally aresupposed to have been moved to the right and put in the plane ofmovement of the jackelevator 1), consisting, essentially, of abarmounted upon a suitable actuator represented as arms I) attached to arock-shaft b the said rock-shaft at or near its opposite ends (see Fig.3) having fast upon it a suitable radius-bar or device I), whichis actedupon by the cam D before described, fast on the shaft A.

The pattern-surface, in order that it may be kept taut and be restrainedfrom swaying at its lower end and in order that it may be kept seatedcorrectly upon a barrel E has, as shown in Figs. 4 and 5, cooperatingwith it a tension-roll D, to the shaft of which (see Figs. 2 and. 3) areconnected links D suitably jointed upon suitable stands attached to Whenthe pattern-surface is kept taut by such roll or rolls, it moves like abelt on pulley, and a single row of pins or studs will keep itin theright position.

I have shown the roll or barrel of the pattern-surface as provided at ornear the middle of itslength with a series of studs 3, which entersubstantially round holes in the patternsurface, and to gain the bestresults and secure great durability of the parts I have shown and preferto reinforce the holes in the pattern-surface with eylets 4.

I have shown the roll or barrel E as provided at or near its ends withpins 5, which enter an elongated hole 6 inthe pattern-surface, the saidhole being 'elon gated to thereby insure the correct entrance of thepins into the holes during the rotation of the roll or bar- I have foundthat if the studs are just the shape of the holes-and there is noopportunity for the studs to move in the holesthat under certainconditions of the atmosphere the studs will not properly enter theholes, and then the pattern-surface will not lie fiat upon the roll orbarrel, and consequently, not being properly supported by the rollorbarrel, will be quickly worn through or destroyed and result inmispicks.

The holes 6, made in the belt-like surface near its side edges, to beentered by the studs 5 of the substantially circular, cylinder or barrelE are separated each from the other for a comparatively shortdistance-say from one-half to one inch apart in practice-and hence thechanges in the length of the belt due to extreme changes in the weather,as statedchangesnowhere more excessive thanin the United States-are soslight between one and the next hole 6 as not to bemateriallyperceptible. When it is considered that the pattern-surfacebelt is from fifteen to twenty inches wide, then it will be understoodthat the expansion or contraction of the belt widthwise between thewidely-separated holes 6 is sufficient to throw the said holes outofalinement with the pins 5 from end to end of the cylinder, andconsequently an endless paperlikc belt cannot be used practicallywithout elongating the holes 6, as I have discovered by practice, in thedirection of the width of the belt. By employing a central row of studs3 upon thecylinder it is possible to divide the widthwise stretchingequally between the center of the belt and the endmost holes.

I experienced great trouble, under climatic changes. common in theUnited States, to use an endless Jacquard belt composed wholly of paper;but I discovered by experiment that the expansion of the paper might 'becontrolled largely as to its extent by lining the paper with a web ofcloth, the cloth web extending, however, across the paper websubstantially from edge to edge. The greatest difficulty from theweather is in the width of the belt. The cloth lining for the paper,besides diminishing the expansion, added very materially to the strengthof the belt and enabled it to wear much longer where it contacted withthe needles, or, in other words, the cloth backed the paper.

I could not derive any material benefit as to counteracting theexpansion widthwise of the pattern-belt by the employment of a series oftapes extending lengthwise of the belt in the line of the holes 6, and Idisclaim, therefore, the use of such tapes.

The shaft E of the roll or barrel carrying the pattern-surface has uponit a suitable lantern-wheel or equivalent device, the pins ofwhich areengaged-by suitable teeth-of a double-actin g pawl e, the direction ofrotation IIO of the said shaft depending upon whether the upper or lowerarm of the pawl is operative. The pawl is mounted upon a movable orswinging fulcrum 6 carried by a lever 6 pivoted at e and having a toe 6An arm 6 of the pawl has a suitable guide through which is extended arod 6 connected loosely to a suitable stud e on the rocker-plate e, thesaid rod near its left-hand end, as shown in Fig. 2, having nuts or ahead 10, against which abuts a spring 12, the opposite end of which actson the arm a of the arm 6.

Fig. 2 shows the pawl in its normal condition, the pattern-chain inpractice being moved in the direction of the arrow, Fig; 2; but shouldit be desired to reverse the direction of the movement of thepattern-surface the rocker-plate 6" will be turned in the direction ofthe arrow near it in Fig. 2, causing the spring 12, acting on the arm a,to turn the pawl-carrier e and put its under arm in operative positionwith relation to the lanternwheel.

The link 0 is provided with a suitable bunter 13, (shown as anadjustable screw held in an ear 14 of the said link,) and as the link ismoved in the direction of the arrow 15, Fig. 2, the bunter strikes thetoe e and swings the'lever e in a direction to carry the pivotal point eof the pawl e to the right, viewing Fig. 2, such movement taking placeduring the time that the rock-shaft O is being turned to cause thepattern-surface to act against and move the needle longitudinally.

The roll or barrel carrying the pattern-surface is rotated during thefirst part of the in ward movement of the arms F. of the rockshaft 0 thelever e at such time resting against the stop 16, Fig. 2, the leverbeing normally kept against said stop by a suitable spring 17,(represented chiefly by dotted lines, Fig. 2;) but as soon as the yokehas acted to turn the roll or lantern-wheel the distance of one tooth,which represents the distance between one and the next operative row ofholes it may be in the pattern-surface, the bunter 13 strikes the levere and moves it, as stated, thus preventing further rotation of the rollor barrel.

It is of great importance to be able to find as speedily as possible theshed next back of the one in which the mispick occurs. In all looms nowmade where a Jacquard chain is used on a pattern-barrel, which is swungtoward and from the needle and also rotated, it is customary to rotatethe barrel as it is being moved away from-the needle, and when the loomis stopped the barrel is always substantially at its greatest distancefrom the needle, and the barrel has always been turned one step andstands with the holes to indicate the next shed ready to cooperate withthe needles at the next inward movement of the barrel carrying thepattern-cards. Now in case of a mispick the operator has to shift thehooks for rotating the barrel, so that it will be turned baokwardlyinstead of forwardly,

and the 100111 is started, usually slowly, and operated partially byhand, but without throwing the shuttle and leaving the weft in the sheduntil the barrel has been turned back from two to three shedsnever lessthan two sheds-and when the proper shed has been reached the operatorwill again shift the hooks and start the loom in regular operation. Inmy invention, however, wherein the pattern cylinder is turned as itapproaches the needle, the row of holes making the last shed is leftfacing the needles when the loom is stopped with the cylinder farthestfrom the needles, and consequently the next shed behind the one with themispick can be reached by but one movement of the cylinder, the operatorhaving only to shift the pawl to put its reverse projection in the lineof movement of the cylinder, and as the cylinder is moved toward theneedles it is rotated back one step and opens without fail the shed nextback of that one in which the mispick occurred. The provision forturning the barrel carrying the belt-like patternsurface during'theinward movement of the barrel toward the cylinder is thereforeproductive of such saving of time that the aggregate in a large millusing many looms becomes a matter of very considerable saving and value.

By the term endless belt I mean to include an endless web ascontradistinguished from a series of separate cards tied or jointedtogether.

Fig. 2 shows the fulcrum e as moved back, as when the needles have beenpushed in.

In practice in this present loom, as in others prior to my invention,the shaft E which carries the shed-forming pattern-surface is alsoprovided with a suitable roll or barrel to carry the shuttle-boxpattern-surface G, composed of like material and operated underconditions similar to that of the pattern-surface E I have combined withthe rocking plate 6 a locking-lever f controlled by a spring f, and, asshown, provided with a roller to enter one or another notch in the saidplate according to the position of the latter. If the roller carried bythe locking device f is in the notch 19 of the plate, then the rod 6acting through the spring and arm c ,will throw into operative p0 sitionthe lower teeth of the pawl to rotate the roll or barrel carrying thepattern-surface, but in a reverse direction.

Referring to Fig. i, it will be seen that I have interposed betweenselecting-rods a and the notched jacks a series of fingers g, pivoted atone end, said fingers preferably carrying antifriction-rolls to actdirectly against the jacks.

It will be obvious to those conversant with looms that my invention,with but slight modifications, may be easily and readily adapted to anyform of loom wherein a jack of any kind is adapted to be put into one oftwo positions at desired times in order that it,or some part of it, maybe acted upon by some sort of a lifter or depressor. For instance, I mayapply my invention to that class of looms of which the Knowles loom,represented in said United States Patent to Knowles, No. 134,992, is atype. I have shown myinvention in Fig. 5 as adapted to such type ofloom, and in said figure h is supposed to represent the elevator and hthe depressor, they consisting of fluted gears adapted to engage toothedgears 71 carried by vibrating levers h pivoted at If, the said leversand toothed gears constituting one form of jack, the toothed gears beingin practice joined by suitable connections 7L5 with the levers h, allcommon to the said Knowles patent, which levers h are in practiceconnected at their ends with suitable cording with the harness-frames.

In Fig. 5 E represents a roll or barrel like the one designated bysimilar letter in Fig. 4, it in practice carrying a pattern-surface suchas provided for in Figs. 1 and 4.

In Fig. 5 I have applied upon the shaft h of the elevator h a cam 72which acts on an arm 77., attached to arock-shaft 71, supposed to be thesame as the rock-shaft O in Fig. 2, suitable arms, as h, depending fromsaid rock-shaft, carrying theshaft of the roll or barrel E In Fig. 5 Ihave also'representedacam, as it, applied to the shaft 71 of thedepressor h, said cam acting upon an arm 71 connected with a rock-shaftit supposed to be the same as the rock-shaft 79 (see Fig. 4,) saidrockshaft having arms 71 corresponding with the arms I) of Fig. 4, whicharms 72. carry a jack elevator Z), the latter acting upon such of theselecting-rods a as may 'have theirlower ends placed in range of itsmovement by or through the'needles a, acted upon by the patternsurface,as provided for in Fig. 4.

In Fig. 5 I have shown a series of fingers g as interposed between theselecting-rods and the jacks 71 i I have omitted from Fig. 5 the meansfor rotating the roll or barrel carrying the patternsurface, butinpractice the means will be substantially the same in construction andprinciple of operation as described and represented in Fig. 2..

In Fig. 3 I have shown a series of levers m which may be employed inconnection with a shuttle box actuating mechanism. (Not shown.) I havein this present case merely shown said lever in order that it may beseen that the same class of pattern-surface which I have described atlength in connection with shed-forming devices and the same selectingrods and intermediate devices may be employed to distribute the levers071 so that in devices which are to be lifted or selected by.

or through the selecting-rod. I therefore consider as within the termjack as herein used any lever or radius-bar which is distributedthroughthe action of a pattern-surface as, for instance, the levers used inconnection with a shuttle-box mechanism.

The pattern-surface may be of any flexible material-such, for instance,as cloth or paper-but paper and cloth combined is considered best.

In Fig. 8 N is supposed to represent a layer of cloth. I

Notwithstanding I prefer that the pawl for rotating the barrel carryingthe pattern-surface shall slide as 'well as turn about a pivot, yet thismy invention is not in all instances to be limited to such a pivot, forit is possible by means of a pawl on a stationary pivot to rotate thebarrel E during the first part of its movement toward the needles, andlet the pattern-surface therefor be carried against and moved in thedirection of the length of the needles to cause them to distribute thejack-selectors, the barrel being locked against rotation so long as thepatternsurface is acting on the needles. A device of this sort is shownin Figs. 9 and 10. In these figures, which are diagrams, (3 is arock-shaft; E, arms thereof carrying the shaft E, on which is the barrelE to carry the pattern-surface,

and O is a locking-lever moving a roll to enter a concavityin theperiphery of a locking-plate attached to the shaft E. C is a spring, anda needles, all as provided for in Figs. 1, 2, and 3. e

In Figs. 9 and 10 T represents a pawl pivoted at T, the fulcrum of thepawl being stationary; and this pawl in practice will have two likearms, one being partially broken off to avoid confusion on the drawings.

Referring to Fig. 9, it by full lines shows the barrel in its farthestoutward position away from the needles a, and in such position its pins60 are to the left of, not against, the shoulder of the upper pawl-arm,and the roll 61 is in a notch of the plate 62. As the rock-shaft O isturned, as described, with relation to Figs. 1 to 3 by the cam O to movethe barrel E to the right, a pin 60 will strike the shoulder of the pawland the rotation of the barrel will be started, and the roll 61 willcome into position on a point between two concavities of the plate 62,as shown by dotted lines, and the spring 0 thereafter acting on thelever C and roll 61, will cause the latter by its pressure on the saidpoint to further rotate the said barrel 1 to complete a movement tobring a n ew row of holes of the pattern-surface in position oppositethe ends of the needles, and the roll 61 then entering the next space inthe plate 62 will lock the same during the further movement of thebarrel to the right, as in dotted lines, Fig. 10. The'roll 61 inrotating the same by pressure against one side of the point referred tocauses the pin 60, just before in engagement with the shoulder of theITO pawl, to be carried back away from the said shoulder into theposition shown by dotted lines, Fig. 10, so that the motion of the rollmay be continued by or through the arms E for a distance equal to thatbetween the said pin and the shoulder of the pawl without rotating thebarrel, and it is during this last part of the movement of the barrel,due to the arms E, that the pattern-surface acts on the ends of andmoves the needles a, longitudinally. lVhen the arms E are swung to theleft to put the barrel again in the f ull-line position, Fig. 0, the pinshown by full lines as at the right of the shoulder of the pawl as, forinstance, the pin Fig. 10-will be again brought into position in frontof the shoulder of the pawl.

In Fig. 3 I have shown the endless belt G as adapted to work the needlesa which in turn guide and move the sliding selectors a into and out ofposition with relation to the jack elevator I), said selectors acting,as shown, against the fingers 9 which in turn act. on the lever m towhich is jointed the rods m in practice extended to the devices foractuating shuttle-box devices of usual or suitable construction, saiddevices not being shown, as they are not of my invention.

It will be noticed in my invention as herein exhibited that the needleswhich are distributed by the Jacquard pattern-surface besides serving asguides for the selecting-rods also directly distribute the saidselecting-rods with relation to the jack-elevator b or device, which,acting on the selecting-rods, effects in turn the distribution of thenotched jacks connected with the harness-levers, the latter in practicebeing connected to their opposite ends by cording with theharness-frames, as in the patents referred to.

In this my invention I have aimed to gain the greatest simplicity ofconstruction coupled with the fewest possible parts compactly arrangedand having strength and durability.
